Abstract

A protective cover and a display device including a protective cover are provided. According to one or more embodiments, a protective cover includes a cover substrate; a first anti-scattering coating layer on the cover substrate; an intermediate layer on the first anti-scattering coating layer; a second anti-scattering coating layer on the intermediate layer; and an adhesive layer on the second anti-scattering coating layer, and the first anti-scattering coating layer and the second anti-scattering coating layer cover an upper surface, a lower surface, and at least one side surface of the intermediate layer.

First claim

What is claimed is:

1. A protective cover comprising:
a cover substrate;
a first anti-scattering coating layer on the cover substrate;
an intermediate layer on the first anti-scattering coating layer;
a second anti-scattering coating layer on the intermediate layer; and
an adhesive layer on the second anti-scattering coating layer,
wherein the first anti-scattering coating layer and the second anti-scattering coating layer cover an upper surface, a lower surface, and a side surface of the intermediate layer, and
wherein a region of the side surface of the intermediate layer not covered by the first anti-scattering coating layer is covered by the second anti-scattering coating layer.

2. The protective cover of claim 1 , wherein the intermediate layer has a smaller area than both the first anti-scattering coating layer and the second anti-scattering coating layer in a plane view.

3. The protective cover of claim 1 , wherein the intermediate layer extends along an edge of the protective cover.

4. The protective cover of claim 1 , wherein a thickness of the intermediate layer is less than a sum of thicknesses of the first anti-scattering coating layer and the second anti-scattering coating layer.

5. The protective cover of claim 1 , wherein a thickness of the second anti-scattering coating layer is equal to or greater than a thickness of the first anti-scattering coating layer.

6. The protective cover of claim 1 , wherein the cover substrate is flexible.

7. The protective cover of claim 1 , wherein the first anti-scattering coating layer and the second anti-scattering coating layer are made of different materials.

8. The protective cover of claim 1 , wherein each of the first anti-scattering coating layer and the second anti-scattering coating layer is made of at least one selected from the group consisting of an epoxy acrylate resin, a polyester acrylate resin, a polyether acrylate resin, a urethane acrylate resin, an acryl acrylate resin, an unsaturated polyester, a urethane resin, an acrylonitrile butadiene styrene resin, and rubber.

9. The protective cover of claim 1 , wherein the cover substrate has a thickness of about 10 μm to about 150 μm.

10. The protective cover of claim 1 , wherein the cover substrate comprises glass, and the glass comprises an ion-exchanged chemical strengthening layer.

11. The protective cover of claim 1 , wherein, when a pen of about 5.7 g is dropped, a drop height of the pen at which the protective cover is broken is about 8 cm or more.

12. The protective cover of claim 1 , wherein the intermediate layer comprises a decorative layer imparting a pattern to the protective cover.

13. The protective cover of claim 1 , wherein the second anti-scattering coating layer is between the adhesive layer and the intermediate layer.

14. A display device comprising:
a display panel to display an image; and
a protective cover arranged on the display panel,
wherein the protective cover comprises:
a cover substrate;
a first anti-scattering coating layer on the cover substrate;
an intermediate layer on the first anti-scattering coating layer;
a second anti-scattering coating layer on the intermediate layer; and
an adhesive layer on the second anti-scattering coating layer,
wherein the first anti-scattering coating layer and the second anti-scattering coating layer cover an upper surface, a lower surface, and a side surface of the intermediate layer, and
wherein a region of the side surface of the intermediate layer not covered by the first anti-scattering coating layer is covered by the second anti-scattering coating layer.

15. The display device of claim 14 , wherein the display panel and the protective cover are flexible.

16. The display device of claim 14 , wherein the cover substrate has a thickness of about 10 μm to about 150 μm.

17. The display device of claim 14 , wherein the intermediate layer has a smaller area than both the first anti-scattering coating layer and the second anti-scattering coating layer in a plane view.

18. The display device of claim 14 , wherein the intermediate layer comprises a decorative layer imparting a pattern to the protective cover.
